A few niggling correction things:
1) Am I correct that Imani's Sending Stones are held by Lorent, Aywin, and Shamal (I had thought Urgan, but Merrick seems to think Shamal).
2) Similarly, Darius has the Lightbringer sword, right? If not, Loklafd could carry it. (He could probably use it instead of his spear, though he likes his spear).
3) Merrick has 1/4 Hit Dice.
@TaranTheWanderer You have it listed as 0/3 but he's Level Four. He's got one left.
4) Don't assume that I'm using NPCs to hint at you - I mean, I suppose that sometimes I sort-of am, but it's really more that any given NPC has its own opinion on what you should do. They won't always be correct. Stryke, being a Drow, would rather get further underground by any means necessary. OTOH, he knows a thing or two about the layout of the place. He suggests you use the Sewer, for sure, but
I am considerably more neutral on the subject. That said, he could be right. He seems like a practical fellow.
